I agree that using upscaled graphics in PCSX2 make them more playable on a modern large TV (Looking at you Gran Turismo 4 in 8k60fps) but I think - because the games _were_ designed to be played on old CRT TVs with scanlines - using an older TV makes the games feel much better. I'm planning making a retro corner with an old TV and older consoles instead of just playing on scaled up emulators.
